1 Claim.

The primary object of my invention is to provide a fuel compound thatcan be used satisfactorily as a substitute for gasoline or otherhydrocarbon oil in internal combustion engines and for 5 otherindustrial purposes, said compound possessing all of the desirablequalities of gasoline and other mineral hydrocarbon oils. My improvedproduct is designed to be independent of mineral oil shortage, lessexpensive than hydrocarbon mineral oil fuel, and to'utilize waste andlow grade materials as a source of production.

In producing my improved motor fuel, I employ raw ingredients, such ascom, com cobs, corn stalks, table refuse, spoiled crops, wood saw dust,wood chips, wood shavings, cellulose, wheat, rye, oats, barley, rice,beet roots, potatoes, peanut hulls, horse chestnuts, and waste andfermented products which are entirely free from coal tar or petroleumderivatives. These products are reduced by fermentation and distillationto butyl alcohol, acetone, ethyl ether, anhydrous ethyl alcohol andvegetable oil, or by chemical synthesis from chemicals and gasesprocured solely from said ingredients. Certain of these resultantingredients may be mixed in proper proportions as hereinafter set forthand the resulting liquid is a motor fuel which will vaporize and whencompressed in an internal combustion engine, will readily ignite andexplode. I have found'that the following ingredients produced as statedabove and assembled in substantially the following proportions willproduce a highly efficient and effective motor fuel:

Per cent (N) Butyl alcohol 38 (95%) .Ethyl alcohol or (ethyl orsulphuric ether) 10 Acetone 30 Turpentine or (toluol) 4 Benzol 18 innersurfaces of the cylinder, piston head and valves; no carbon knockoccurs, and the engine produces good heayy pulling characteristics withsubstantially no overheating effect. My improved fuel compound can bereadily compressed to a highly efllcient extent, has a high flash test,is permanent and will not separate into constituent parts after longstanding or being subjected to ordinary changes of temperature, issubstantially completely consumed by combustion when used, 10 is moreeconomical than most other fuels when used to operate internalcombustion engines, and may be used in place of gasoline and other fueloil most effectively.

The proportions of ingredients used may be 15 varied substantially 5%either way to suit varied, conditions. Also up to 8% of ethyl orsulphuric ether may be added to replace an equal amount of ethyl alcoholor acetone for easier starting of the motor and to increase vaporpressure.

Primarily the butyl alcohol provides power accompanied by highvolatility to the product. The ethyl alcohol and acetone increase thevapor pressure and make starting in cold weather easier. The turpentine(or toluol) is used to increase the air fuel ratio and to insure theproper heat content. The benzol increases the air fuel and acts as astabilizer as well as to increase the heatcontent. As the butyl alcoholand ethyl alcohol normally do not have'the proper amount of heat unitsto compare with the type of fuel being used I in present day equipmentand require a lower air fuel ratio, it is desirable to substitute theethyl alcohol, acetone, turpentine, ether and benzol in varyingproportions as stated so as to buildup the heat units as well as toincrease the vapor pressure. I

I have stated generally the ingredients and proportions thereof of whichmy improved fuel may be composed but I desire to have it under- 0 stoodthat the ingredients inay, within the doc-z trim of equivalents bevaried in proportion and otherwise, within the scope of the followingclaim.

I claim:

A fuel, employing a mixture of ingredients fermented and distilled fromfermentable products, consisting of butyl alcohol'38 parts, ethylalcohol 10 parts, acetone 30 parts, turpentine 4 parts and benzol 18parts.
